METHOD OF PRODUCING RAISED DESIGNS IN COLORS.

SPECIFICATION forming part of Letters Patent No. 438,397, dated October14, 1890.

Application filed May 23, 1890. Serial No. 352,845. (No model.)

To all whom it may concern:

Be it known that I, THOMAS BENFIELD, a subject of Her Majesty the Queenof Great Britain, and a resident of Newark, in the county of Essex andState of New Jersey, have invented certain new and useful Improvementsin the Method of'Producing Raised Designs in Colors,- of which thefollowing is a specification.

My invention relates to a new method of producing raised metaldesigns incolors; and it consists substantially in first partially producing orpartially striking up the design by means of a suitable die; secondly,in soldering or otherwise securing small pieces of different-coloredmetal to such partially struckup design; thirdly, in again subjectingthe design to the action of a die for the purpose 'of completely orentirely striking up the design, and, finally, finishing the design byengraving or otherwise.

As will be hereinafter understood, my new method of producing designs isapplicable to all cases where surface ornamentation is to be producedupon or in metal and is not limited to any particular design or designs.As I have heretofore used or employed my new method in the ornamentationof watch-cases, I will describe the same as employed for that purpose,the design in this instance being intended to represent a camping scene,as shown in the accompanying drawings, in which Figure I represents thelid or back of a watch-case having a design partially struck up orpartially formed thereon in relief. Fig. II is a similar View showingthe back or lid of the case after the small pieces of differentcoloredmetal have been soldered or secured thereto. Fig. III is a similar Viewshowing the lid or case after being subjected a second time to theaction of a die and after being touched up or finished up by hand.

In carrying out my method a metal plate or blank is first subjected tothe action of a die, the purpose of which is to partially form thereonin relief the design intended to be imparted to the case, the design atthis stage being only partially imparted to the metal, the purpose orobject of this operation being to produce thereon a clear outline of thedesign,in order to serve as a guide for the workman to properly arrangeand secure thereto small pieces of different-colored metalas, forinstance, as will be seen by Fig. I of the drawings, the outline of thecamping scene is imparted thereto by the action of the die, the raisedportions a of which are comparatively fiat, in order that small piecesof difierent metal B may be securely soldered or fastened thereto, thecolors of said small pieces of metal B depending of courseupon thedesign intended to beproduced upon the case' as, for instance, thoseportions of metal lettered or, intended to represent grass and theleaves of trees, will most properly be yellow and green, and, ifdesired, the trousers of one or more of the men appearing in the designmay be of steel color or red and the coats of a different color to formor produce the necessary contrast, and so on through the design. Afterthe small pieces of metal B have been properly arranged and soldered tothe design the lid or back of the case is again subjected to the actionof the die for the purpose of completely raising those portions of thedesign intended to be produced in relief, and also by means of thepressure exerted upon the die and the metal placed therein to bury thesmall particles of metal B in the metal of the case, and in order, also,to spread the small metal pieces B, so that their edges, Wherenecessary, will be properly joined or united and all trace or traces ofsaid edges removed. The lid or back is then removed from the die, and,if necessary, finished by engraving or otherwise to impart to the designa more finished appearance.

It will be understood that this method of producing raised designs incolors is not limited to any particular kind or character of metal,excepting in so far that the metal shall i be such as will allow thedesign to be pressed;

thereon or therein by means of a die; nor is the method limited to anyparticular color, colors, or tints of metal, nor to the number of such,as it is obvious that the number of colors which may be used in a designis only limited by the size of the pieces B and the number thereof whichmay be soldered or se cured to the case; nor doI intend to limit myclaim to any particular design, as an infinite number of designs may beproduced in relief in colors by my method, nor to the application of mymethod to Watch-cases, as such may be employed in ornamenting jewelry ofall kinds.

Having fully described my invention, What I intend to claim as new, anddesire to secure by Letters Patent, is-

1. The method hereinbefore described of producing designs in colors,consisting in, first, subjecting the article to the partial action of adie; secondly, soldering or otherwise securing different-colored piecesof metal to the partially-formed design; thirdly, subjecting the designto the action of a die.

2. The method hereinbefore described of THOMAS BENFIELD.
